LAND-PULVERIZER AND CLOD-CRUSHER.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed December 3, 1904. Serial No. 235,360.

To all whom it may concern.-

Be it known that 1, ROBERT J. BUSWELL, a citizen of the United States, residing at VVellington, in the county of Sumner and State of Kansas, have invented a new and useful Land- Pulverizer and Clod-Crusher, of which the following is a specification.

This invention relates to that class of implements for tilling the soil which serve to pulverize its surface, to break up the clods, and to leave the soil in fit condition for the reception of seed and which come under the general head of harrows, pulverizers, and crushers.

The present invention has for its object to simplify and to improve the construction of machines of this class and to provide a device which shall possess superior advantages in point of simplicity, durability, and general efficiency.

l/Vith these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes and modifications may be resorted to within the scope of the invention and without departing from the spirit or sacrificing the efficiency of the same. In said drawings, Figure 1 is a-top plan View of a machine constructed in accordance with the principles of the invention. Fig. 2 is a sectional elevation of the same. Fig. 3 is a top plan view of a part of a machine illustrating a modification. Fig. 4: is a perspective detail view. Fig. 5 is a sectional elevation illustrating a further modification.

Corresponding parts in the several figures are indicated bylike characters of reference.

The frame of the machine is composed, es-

' sentially, of two side members, each consisting of a diamond truss, the upper and lower members of which are spaced apart at the ends thereof by journal-boxes 1 1 and intermediate of their ends by struts 2 2, the truss members themselves being designated 3 3. The journal-boxes 1 1 at the front and rear ends of the frame afford bearings for shafts 4: 4, carrying cylinders 5 5, which in the form of embodiment of the invention illustrated in Figs. 1 and 2 are provided with radially-extending spikes or teeth 6 6.

Suitably supported upon the truss-frame in rear of the respective rollers are brushes 7 7, each of which is preferably constructed of a pair of corrugated metal strips 8 8, having the wire bristles 9 secured between them by means of transverse clamping bolts, rivets, or other suitable clamping means 10 10. The forward brush may be supported directly upon the lower truss member, as will be seen in Fig. 2, while the rearward brush is supported upon brackets 11, which may form rearward extensions of said lower truss member, it being understood, however, that the location of these brushes may be varied.

12 designates an axle which extends transversely between the struts 2 2 of the side members, said axle being provided at the ends thereof with transporting-wheels 18. Suitably connected with the ends of the axle between the truss members of the roller-carrying frame and the transporting-Wheels 13 are the forwardly-extending side members 14; of the draft-frame, which is composed, in addition to said axle and side members, of a front cross-piece 15, with which the-tongue 16 and hounds 17 are suitably connected. A seat 18 for the driver is supported upon the draft-frame, and the latter is also provided with a curved shield 19, which is disposed in advance of the front roller for the purpose of protecting the driver from dust and dirt.

The axle is provided with wear and guide plates 20 (shown in detail in Fig. 4) and each consisting of a base-plate 21, provided at its upper and lower edges with perforated ears or lugs 22 engaging the upper and lower sides of the axle, with which said wear and guide plates are suitably connected by screws, bolts, or other fastening means. The base-plates 21 of these devices are also provided at the sides thereof with laterally-extending flanges 23 engaging the struts of the side members of theroller-carrying frame with which the axle of the draft-frame is thus connected for the purpose of applying draft to the rollercarrying frame. It will be seen, however, that the said draft-frame and the roller-carrying frame are capable of vertical movement independently of each other. Hence when the surface of the soil is rough or un even the rollers, as well as the transportingwheels of the draft-frame, will remain in operative contact with said surface, and the work will be evenly and steadily performed.

Under the modified form of the invention illustrated in Fig. 3 of the drawings, the rear spiked roller has been detached and a smooth roller (designated 24) has been substituted in its place.

Under some circumstances a rear roller may be altogether dispensed with, and again under some circumstances the frame of the machine may be constructed to carry more than two rollers, the general characteristics of the machine being, however, retained. Such modifications are considered to be entirely within the scope of the invention, and a special illustration thereof is considered unnecessary.

When it shall be desired to provide positive means for adjusting the rollers with relation to the carrying-frame for the purpose of carrying said rollers elevated from the ground,

the construction especially illustrated in Fig. 5 of the drawings may be resorted to. Under this modification a pair-of toothed segments 30 are mounted upon the axle 12 of the frame, and concentrically to said segments are pivoted levers 31, equipped with spring-actuated catches 32 of ordinary construction to engage said toothed segments for the purpose of retaining the hand-levers in any position to which they may be adjusted. Said handlevers are provided at their lower ends with outwardly-extending arms 33, terminating in saddles 34:, having side flanges 35, and which form seats or supports for the top members of the trusses which constitute the sides of the roller-carrying frame. It will be readily 'seen that by manipulating the hand-levers 31 the roller-carrying frame may be raised to an extent sufficient to support the rollers clear of the ground, as is desirable for the purpose of transporting the machine from one place to another. While this adjusting mechanism is obviously useful and desirable, it is not absolutely essential in the construction of the machine.

In the construction of the improved machine no limitation is made as to the material employed or with regard to size and proportions of the parts. The roller-carrying frame may be preferably constructed of wrought-iron, while the rollers may be made of cast-iron and the teeth or spikes of steel, the draft-frame being preferably constructed of wood. While the construction of the wire brushes herein described may be held preferable, said brushes may be constructed in any suitable and appropriate manner.

The operation of this invention and its advantages will be readily understood from the foregoingdescription,taken in connection with the drawings hereto annexed. hen themachine progresses over the field, the sharp teeth will readily penetrate and crush the clods into fragments, which are completely pulverized under the weight of the rollers.

This machine will obviously be of lighter draft and more effective in its operation than a drag-barrow of ordinary construction, and it permits the operator to ride Without materially increasing the work of the team.

Having thus described the invention, what is claimed is 1. In a machine of the class described, a roller-carrying frame having diamond-truss side members provided with spaced struts, a draft-frame including a wheel-carrying axle guided vertically between said struts, and flanged guide members connected with the axle; said guide members comprising each a base-plate having lugs engaging the axle and lateral flanges engaging the struts.

2. In a machine of the classdescribed, a roller-carrying frame having diamond-truss side members provided with spaced struts, a draft-frame including a Wheel-carrying axle movable vertically between said struts, and a seat and a dust-shield supported upon saiddraft-frame.

3. In a machine of the class described, a roller-carrying frame having side members, a draft-frame including a wheel-carrying axle, rack-segments upon said axle, and hand-levers pivotally connected with said rack-segments and having laterally-extending arms provided with seats for the side members of the rollercarrying frame.

4. In a machine of the class described, a roller-carrying frame having side members provided with spaced struts, a draft-frame including a wheel-carrying axle extended between said struts, rack-segments supported upon said axle, hand-levers pivoted upon said rack-segments and having spring-actuated catches engaging the latter, and arms extending laterally from the lower ends of said levers and terminating in saddles having side flanges forming seats for the side members of the roller-carrying frame.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

ROBERT J. BUSWELL.
